The Power of Compound Interest
Albert Einstein allegedly called compound interest "the eighth wonder of the world." Here's why:
$10,000 invested at 7% annually:
- After 10 years: $19,672
- After 20 years: $38,697
- After 30 years: $76,123
Compound Interest Formula
``
A = P(1 + r/n)^(nt)
``
Where:
- A = Final amount
- P = Principal (initial investment)
- r = Annual interest rate (decimal)
- n = Number of times interest compounds per year
- t = Number of years
Compounding Frequency Impact
$10,000 at 10% for 10 years:
| Frequency | Final Value | Annual$25,937 Quarterly$26,851 Monthly$27,070 | Daily | $27,179 |
